Sticky cost behaviour: evidence from small and medium sized companies

This paper investigates whether cost stickiness occurs in small and medium sized companies using a sample of Italian nonlisted and listed firms during the period 1999–2008. Our findings show that cost stickiness emerges only for the total cost of labour and not for selling, general and administrative (SG&A) costs, cost of goods sold and operating costs. Stickiness of operating costs is only detected in a sample of listed companies. We further contribute to the literature on sticky cost behaviour by discussing critical issues associated with the extant approach of empirical analysis and interpretation of sticky cost behaviour.     

The influence of formal and informal sales controls on customer-directed selling behaviors and sales unit effectiveness

Adaptive selling (AS) and customer-oriented selling (COS) constitute two key customer-directed selling behaviors for the success of the modern sales force. However, knowledge regarding the organizational factors that can induce salespeople to engage in those behaviors is strikingly limited. Against this background, we develop a comprehensive model that delineates the influences of formal and informal sales controls on AS and COS and, through them, on sales unit effectiveness. Based on a sample of sales managers in a major European Union country, we present new evidence that (a) formal and informal sales controls exert differential impact on salespeople's AS and COS behaviors; (b) AS directly and positively influences sales unit effectiveness; (c) COS affects sales unit effectiveness only indirectly, i.e. by fostering AS; and (d) outcome and cultural controls directly improve sales unit effectiveness. We conclude with a discussion of our findings for academics and practitioners.     

Social Network and Weight Misperception among Adolescents

It is recognized that public health intervention targeted toward changing lifestyle behaviors to reduce overweight status is a considerable challenge. It is important that individuals recognize their overweight status as a health risk in order for an effective change in lifestyle behaviors to occur, and growing evidence suggests that actual weight and perception of weight status often do not match, especially among adolescents. In this article, we explore the extent to which exposure to heavier peers and parents affects misperception of their own weight status by adolescents. Using data from a nationally representative sample of adolescents, we estimated instrumental variable models with school‐level fixed effects to account for bidirectionality of peer influence and environmental confounders. Our results indicate that individuals who live in an environment that exposes them to overweight/obese parents and heavier peers tend to misperceive their weight status and think of themselves to be of lower weight than they actually are. Our analysis also revealed differential effects by gender and type of peers.     

Alitalia – The failure of a national carrier

The paper examines the case of Alitalia, Italy’s former flag carrier, as a case of a state-managed failure. The history of the airline is characterized by a continuous decline in its competitive position since the progressive liberalization of the European aviation market. The root cause of this decline lies in the carrier being mainly used as a political tool rather than operating as a competitive firm. In a liberalized market this doomed Alitalia to failure, which was artificially delayed by numerous state financial and regulatory interventions. The paper starts with a historical overview of the most important events in recent Alitalia history. Thereafter the main causes of the airline’s weak competitive position relative to other European carriers are analyzed. We argue that the underlying causes of the decline were continuous political protection, lack of strategic views in favor of short-term objectives, and poor managerial decisions.     

Inside innovation persistence: New evidence from Italian micro-data

This paper contributes the analysis of the persistence of innovation activities, as measured by different innovation indicators and explores its past and path dependent characteristics. The study provides new insights on the role of R&D investments in innovation persistence and analyses differentiated patterns of persistence across product and process innovation, by accounting for complementarity effects between the two types of innovative behaviour. The empirical analysis is based on a sample of 451 Italian manufacturing companies observed during the years 1998–2006. Results highlight the relevance of innovation persistence. The highest level of persistence is found for R&D-based innovation activities, witnessing the actual presence of significant entry and exit barriers. Moreover, we obtain more robust evidence of persistence for product innovation than for process innovation when complementarity effects between the two types of innovation are accounted for.     

Discrimination,technology and unemployment

I study the interaction between discrimination and investment using a directed search model where firms decide the capital intensity of their production technologies before being matched. Discrimination makes some workers cheap to hire. As a consequence, some firms might save on capital costs adopting labour intensive technologies. This framework allows one to reconcile search models with three well-known facts regarding the labour market outcomes of minority workers: low wages, high unemployment and occupational segregation. Furthermore, the model questions the role of equal pay legislation in reducing inequality since removing this restriction, i.e., allowing firms to post type-contingent wages, eliminates the negative effects of discrimination on investment and wages.     

Food policy research for improving the reform of agricultural input and output markets in Central Asia

Agriculture is a significant component of the Central Asian economies. Since independence, the republics have implemented agricultural reforms in varying measure, yet production has fallen sharply across the region. The more ambitious agricultural reform programs have included measures aimed at liberalizing agricultural marketing, trade and prices. However, so far the expected supply response has yet to emerge. The objective of this paper is to highlight key policy and research issues surrounding reform of agricultural markets. It summarizes the main features of agricultural performance since the reforms, highlighting trends in grain and cotton, livestock, input use, and trade and analyzes key constraints to improvement of the sector, emphasizing price policy, sequencing problems, and institutional weakness. It presents a research agenda by identifying the main research needs for better agricultural policy design. It calls for more research on input and output market efficiency, private sector development, the effects of reform on farmers, sequencing issues, comparative advantage, water management, land tenure and farm size.     

Banking and the role of money in the business cycle

This paper enriches a standard New Keynesian model with a simple banking sector to investigate the role of money in the business cycle. Maximum likelihood estimation of the model suggests that money balances play a significant role in explaining the intertemporal allocation of consumption and the dynamics of inflation as described by the forward-looking IS and Phillips curves. Nonetheless, the responses of the model’s variables to shocks remain qualitatively similar to a model without money, suggesting that the omission of money balances leaves the model’s transmission mechanism unaffected.     

The Choice of the Working Secto in Transition: Income and non-income determinants of sector participation in Kazakhstan

This study compares the individual, household and location characteristics of private employees, the self-employed, the unemployed and the economically inactive in Kazakhstan making use of a 1996 World Bank Living Standards Measurement Survey. The purpose is to understand whether the process of transition has determined a selection of workers exiting the state sector and entering the three relatively new 'pools' of private employees, self-employed and unemployed. An 'occupational choice' model is used to explore the determinants of sector participation. It is found that income opportunities are similar between the private and self-employment sectors, that the private sector is not necessarily the workers' first choice and that non-income determinants including local economic and labour market conditions and household related factors explain better than income the choice of the working sector. Self-employment seems to be a key sector in understanding the mechanisms of sector choice and the reallocation of labour. Unemployment appears as a choice of last resort and made by truly 'rationed' individuals.     

The impossibility of compromise: some uniqueness properties of expected utility preferences

Summary. We focus on the following uniqueness property of expected utility preferences: Agreement of two preferences on one interior indifference class implies their equality. We show that, besides expected utility preferences under (objective) risk, this uniqueness property holds for subjective expected utility preferences in Anscombe-Aumann's (partially subjective) and Savage's (fully subjective) settings, while it does not hold for subjective expected utility preferences in settings without rich state spaces. Indeed, when it holds the uniqueness property is even stronger than described above, as it needs only agreement on binary acts. The extension of the uniqueness property to the subjective case is possible because beliefs in the mentioned settings are shown to satisfy an analogous property: If two decision makers agree on a likelihood indifference class, they must have identical beliefs.
